13 Claims.

This invention relates to toilet seats of the type having a core of woodor other similar material chosen because of its lightness but having theproperty of rapidly decaying or rotting away when exposed to moistureand having a coating or envelope of plastic, decay resistive materialsuch as hard rubber. The invention particularly relates to seats of thistype which have hinge members secured thereto, after the seat has beenfabricated, by means of machine screws or similar fastening devices.Such hinge members may be either coated with hard rubber like the seator they may have a metal nish such as nickel plate or chrome plate. Thehinge member may be attached to the seat by the seat manufacturer or theseat may be sold by the seat manufacturer to a purchaser who obtains thehinge member from other sources and attaches it himself.

In seats of the character described in the foregoing paragraph there hasbeen heretofore considerable difficulty experienced in preventingmoisture from entering the opening provided for the attaching means andfrom reaching the wood and eventually causing the decay thereof.

It is one of the objects of the present invention to provide a seat ofthe character described in which water cannot reach the wood core andcause deterioration and decay.

It is a further object of the invention to provide a seat in which thewood core is completely protected from moisture prior 'to the attachingof the hinge so that the core will always be moisture proof regardlessoi any carelessness in workmanship in attaching the hinge member or poorquality of iit in the hinge member.

It is a further object of the invention to provide strong, rugged anddurable attaching means for such seats.

It is also an object of the invention to provide a seat of the characterdescribed which shall be simple and economical to manufacture,attractive in appearance, and one that shall have a long life inservice.

The foregoing and other objects of the invention will appear to thoseskilled in the art to which it appertains from a consideration of thedescription of the diiierent embodiments thereof given in the followingspecification taken in connection with the accompanying drawings inWhich,

Fig. 12 is a vertical section taken on the line I2-l2 of Fig. 11; and

Fig. 13 is a plan view of the wooden core shown in Figs. 11 and 12before the enveloping coating 35 has been molded therearound.

Referring to the drawings more in detail, the reference character Ilindicates wing-like cores of wood or similar material which are coveredthroughout with a coating l2 of rubber or other 40 plastic material toenhance the appearance and increase the durability of the seat. Near therear of each core Il a vertical slot I3 is provided which extendsupwardly from the under side of the core and also extends transverselysubstan- 45 tially the entire width of the core. Each core l l is alsoprovided with one or more openings lil which may be conveniently drilledor bored from the rear edge of the core and which extends horizontallythrough and beyond the slot I3 into the 50 wood of the core on the sideof the slot toward the front of the seat. These openings are positionednearer to the bottom side of the core Il than to the top side and theyare open to the outside of the core on the under side thereof as 55indicated at I5. A metallic plate or insert IS is positioned within theslot i3 and serves as a reinforcing member for the core and as a memberto which the hinge member to be presently described may be fastened. Itwill be noted that the upper side of the seat has both corners I1rounded and the plate or member IG has its corresponding corners S5 alsorounded so that it may extend substantially across the entire width ofthe seat without protruding at the corners. It should be stated that themember I6 is not provided with the tapped holes as shown in Fig. 6 whenit is rst placed in the slot i3 in the core I I.

With the plate or member I8 in place in the core the rubber coating ismolded about the core and plate. or flows into the openings I4 on bothsides of the plate or insert I13, the cylindrical portion of rubber onthe side of the plate toward the rear being indicated at I3 and thatportion toward the front being indicated at 2. It will be noted that therubber fiows into the space provided therefor from the rear edge of theseat and also through the opening on the under side of the seat at I5.The appearance of the seat at this stage of manufacture is shown inFigs. 2 and 3. The seat is then drilled from the rear at the center ofthe cylindrical portions It now filled with rubber with the proper sizedrill for tapping the plate IS for machine screws, the drill preferablyextending into the portion 2B a slight distance so that the machinescrews will utilize the full thickness of the metal of the plate I6 forholding purposes. The portion I9 of rubber toward the rear is thendrilled or roamed to provide an opening 2l of a diameter which willreadily receive the body size of the machine screw. Finally the plate IGis tapped as indicated at 22.

It will be seen that this method of manufacture leaves the openings forthe machine screws which hold the hinge member to the seat entirelylined with the rubber coating which covers the outside of the seat.There is a lining of rubber 23 around the opening 2I on the side of theplate I5 which is nearest the rear of the seat which lining extends fromthe outside coating I2 to the plate I6 and completely protects the woodcore I I at this part of the seat. In a similar manner the portion 26completely surrounds the tapped opening therein and is molded againstthe plate I6 so as to effectually seal the core II from the entrance ofany moisture which might enter through the opening for the screw.

In the form of seat shown in Figs. 7 to 10 inelusive, which is of theclosed rear type, there is provided a single core 3l. This is coveredwith a coating 32 of rubber. The general form of insert 33 provided inthis case is shown in Fig. 10 and comprises a plate 3d having two wings35 and 36 reinforced by a rib 31 extending across the back and integralwith the plate. The wood core 3l is provided with a slot 38 extendinginwardly from the rear of the seat to receive the plate 34 with itswings 35 and 35. The slot is preferably cut into the core a littledeeper than the corresponding dimension of the plate so that a portionof the rubber can flow into the space thus left as indicated at 39 andbind the insert 33 firmly in place in the core. 'Ihe rear of the core 3|is also provided with a recess 40 for the rib 3l. The core 3I has a pairof vertically extending passages 4I positioned so that they will lieadjacent to the rib 3'I when the insert 33 is in place as will beclearly seen from an inspection of Fig. 7. The wing 35 is provided withan aper- At the same time the rubber is pressed v ture 42 and the wing3S is provided with an aperture 43 so positioned that when the insert 33is in place in the core the apertures 42 and 43 are in verticalalinement with the respective passages 4I and thus provide a pair ciunobstructed openings from the tcp to the bottom of the core 3 I.

After the insert 33 has been put place the rubber is molded around thecore and insert filling the passages 4I in the core and the apertures 42and 43 in the wings 35 and 36 and also lling the space at 39. There isthus provided a bond of rubber 4 in each of the passages 6I between thcLipper and lowei` coatings of rubber. The seat after the moldingoperation appears as shown in Fig. 8. Holes 45 are then drilled andtapped from the rear of the seat which holes' extend through the coating32 at the rear of the seat, through the rib 37 of the insert, and intothe bond of rubber M behind the rib 3i. t will be noted that no mattei'how carelessly a hinge member may be secured to the rear of the seatthere is no possibility of any moisture passing along the screw used forsecuring the hinge and reaching any part of the wood.

In the modification shown in Figs. ll, 12, and 13 there is a wood core5I through which there are provided a plurality of vertically disposedapertures 52. During the molding operation which applies a coating 53 ofrubber or other material to the outside of the seat there is also moldedas a lining to each of the apertures 52 a cylindrical sleeve or liningor coating of rubber 54. A hinge member 55 is provided with a pair ofhorizontally disposed plates 5G adapted to rest against the under sideof the seat and each plate has a plurality of apertures 51 whichregister with the rubber coated apertures 52. A plate 58 is positionedabove the seat and has a plurality of apertures 53 which also registerwith the apertures 52. The plates 56 of the hinge member and the plate58 are held rigidly together and to the seat by means of bolts @il andnuts BI. It will be noted that the lining 5t serves the double purposeof protecting the wood from moisture and also bonds the upper coating ofrubber to the lower coating of rubber and greatly reduces the tendencyfor the rubber coating to break away from the wood core. As shown in thedrawings the hinge member 55 is provided with a rearwardly extendingportion through which extends a cylindrical opening 53 for the receptionof a bearing pintle but the precise form of hinge construction is notpart of the present invention as it is obvious that various other formsof hinge construction may be employed as well as the form shown.
